Boy, are we green with envy!
At the film’s premiere, the new mom stylishly flaunted her fab post-baby body in a gorgeous red floor-length Lanvin gown. Earlier in the day, she attended a photo call in a fitted emerald green Roland Mouret dress.
In addition to her svelte new figure, Blair also celebrated another mommy milestone — traveling solo with baby Arthur for the first time!
“Off to Venice for Dark Horse with Baby Saint. St. Christopher protect us. Daddy, we will see you back home soon.” she Tweeted before jetting off.
